//! Per-tenant audit log infrastructure (v0.8.0 P4).
//!
//! Every mutating MCP tool emits an audit row from inside the writer-
//! actor's SQL transaction (atomic with the audited write). Every query
//! emits an audit row via a bounded mpsc channel drained by a dedicated
//! tokio task — async, batched, never blocks the query path.
//!
//! See `docs/dev-log/0090-v0.8.0-implementation-plan.md` §2 Priority 4
//! for the design rationale. ADR-0004 (P7) folds audit emission into
//! the per-tenant writer-actor invariants.
//!
//! ## Modules
//!
//! * [`log`] — `AuditEvent`, `AuditOperation`, `AuditWriter`,
//! `purge_older_than`.
